Photovoltaic pumping systems. Design qualification and performance measurements1 Scope and object This International Standard defines the requirements for design, qualification and performance measurements of photovoltaic pumping systems in stand alone operation. The outlined measurements are applicable for either indoor tests with PV generator simulator or outdoor tests using a real PV generator. This standard applies to systems with motor pump sets connected to the PV generator directly or via a converter (DC to DC or DC to
